I am cut and pasting this from Wikipedia: Ratings So You Think You Can Dance premiered with over 10 million viewers in 2005. For Season 1, it was the #1 summer show on television. However, when NBC's America's Got Talent premiered in the summer of 2006, it took the title of "#1 summer show" and, over the past few years, has broadened its lead. In summer 2009, SYTYCD premiered strong with a 3.4 rating in its target demographic, although with the start of America's Got Talent roughly a month later in the same timeslot, Dance fell to #4 on the ratings board. It continued to lose viewers throughout the summer of 2009 and ended up with an average of approximately 8 million viewers. Fox then moved SYTYCD to its fall 2009 schedule where its ratings continued to decline; hitting an all time series low of 4.6 million viewers for a "special" episode hosted by Nigel Lythgoe on September 2nd, 2009. The move to the fall was short-lived. After dropping to an average of 6 million viewers, Fox moved SYTYCD back to the summer in 2010. With Mia Michaels replacing Mary Murphy and former contestants termed as "all stars" being used as partners, the ratings for Dance have continued to slide to all-time series lows; dropping to just 5.6 million viewers on July 15, 2010. For Season 7, Dance is averaging just over 5 million viewers each night while similar shows such as Wipeout and America's Got Talent have seen their numbers increase significantly in the summer of 2010. Assuming that Wikipedia is right, what do you think explains the fall in viewership?
